This book's title: I Somehow Joined the Audience Interaction Group as the Glory Faded
The existing title can't be changed for now. The character names are completely different from those in the show, so how else am I supposed to change it?
Special note: Please don't overthink this, don't relate it to real life, and don't take it too seriously... (Brain storage: Please leave your brain here. Thank you!)
A car accident and a super-smartphone bring Mai Zi into the drama The Glory Fades. He takes over the body of the former Mr. Mai, now a fool, and regains his senses. Inside the drama, he finds himself in an audience interaction group and wanders through the world of Blossoms Shanghai, experiencing its splendor and watching it all fade away... (Main plot 1)
Through the audience interaction group, Mai Zi discovers that he is not only inside a drama, but that his super-smartphone also connects him to otherworlds and even parallel worlds. With Nishang's help, he establishes his own Mai Zi Film and Television Company in another world and embarks on a career in entertainment, from short videos to short dramas. He fills a gap in that world's video-streaming market, drives the development of its entertainment industry, earns himself fate and fortune, and sets out on the path to immortality. (Main plot 2)
